IMPROVED STREET-SWEEPER.

T0 ALL WHM` 'IT MAY- CONCERN:

' I t Be it known that lwe, Rossum Y. McCoNNELL and Gsoues Parsons, of Rochester, in the county of Monroe,

-. and State of New York, havelinvented certain new and useful Improvements in Street-Sweeprs;" and we do hereby declare that the followingis a. full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 :is a. side elevation of our invention.

Figure 2 is a vertical longitudinal section of parts, as shown in lig. 1.

'Figure is a rear view of the driving-pinion and its clutching-apparatus. v

Figure 4 is atop view of the counter-incli`ncd planes, throughv which the clutch-lever operates.4

Figure 5 is a transverseseetion of 'one of the broom-bars, B, detached and somewhat enlarged.

Like letters o f referencefindicate corresponding'partsin all the figures. f

The nature of this invention will be betterl nnderstoodbyre frencefto the drawings and specification.

The frame ot the machine is supported upon four suitabley carrier-wheels, the rear two acting as drivingwheels Vfor the broom-shaft. To each of these wheels s rigidly attached a spur-wheel, S. The counter-shaft l is so hung' thatA the pinions'a are always in 4gearwith the' vspur-wheels lS. The pinionhsare hung loosely upon the shafts, but are coupled to it by means of the feathered 'clutches c. The spiral spring 1 1 (fig. 8) forces the" clutch against the pinion, but will yield, and -permit thepinion toV travel backward if the carrier-wheel on that side of the machine happens -to-lae turned backward,'as when'turning around, while the pinion on tho'opposite Aend will continue to drive the shaft. This shaft drive'sthe'rbroom-shaft byby,the' chain C (tig. 2.)` The Ghain'C may be tightened at any time by means ovthaelamping-bolts in'thestrapsmawhichare-made'doubleone'of' them havingslots for the bolts to 'pass througln'and the` other, round lioles'to it the bolts. One-l1alf of each strap is connected to the frame at points above and below the countershaft,and eqnidistant'from it. The other portion of the straps is similarlyI hinged to a plate, d@through which the broonilshaft revolves. There is `a suspension-rod, r, attached to the upper end of this plate, on eachA side of the machine. These rods connect with a short arm, g, at each en'cl'of the rock-shaft Gr, the arm h of which connects with the adjusting-rod d, avhich is gaugcdby the threaded hand-'wheel w'.' It will be se'en that by this means the broom-shaft is raised or lowered in nearly a verticalV line, underl the axle of the carrier-wheels W, andlield'in the desired adjustment. The clutch. c is thrown out. of gear and held there by the operator, by meansof the hand-leverD, rock-shaftx, rod f, and lever 7:; which latter is pivotedV to the coupling c, as shown'in 3, which is drawn toward the side of the frame of 'the machine by means of the reversed or counter-inclinedv planesm, shown `in 4, the lever' being drawuinto the contracted portion of the plates m. The broom-bars 1?4 maybe made as shown in iig. 5, the plate t being drilled or punched, to receive the rattans, and the woodenbar g, grooved or channclled,"to-` receive the fold or bow of the materials constituting the brush pant. The plates, after' being lled, are bolted to the wooden bars, as shown. There may be ten or more broom-'bars "attached to the shaft I1. We construct the dirt-pan F about as shown in the drawings,l and suspend it to the frame by the straps u. The hinged apron E is placed' and held in any desired position bythe lever u and the jointed rods w', 'g. 2. It is raised and dumped by mcansof a suitable crank-shaft,-Z, and chains.` The forward whecls, W, are attached to a very short .axletrec, so as to facilitato turning around. This end of the ma'chinentay be carried upon suitable springs. The broom-shaft boxes may be hung in a single adjnstablorigid'nrm, if desired,`having the countersbaft a tor'its` axial point. The `Abrooms are made to rise Vand fall wi-ththe surface over whiellthy'pasgby being arranged directly l,under the axle of the carrier-wheels W. The machine may be entirely encased Vexcept at the bottom, from theV rezi'r edge of the hinged apron E, to a point back of the broom-shaft, toconliue the dust.

What we claim as our invention, and desire to sccureby Letters latent, is= l" i 1. The pinio'ns a ot the counter-shaft combined with carrier-wheels W of strecbsweepers, by suitable vsliding clutches, c, all arranged nubstantially as shown anddescribcd, and for the purpose of `equalizing the strength and efficiency of those portions of thc machine. i j

2. The broom-shaft I: and the countershaft e, arranged substantially as shown, being held by means ofthe `adjustable rigid straps y, for the purposes sct forth. V- I i 3.l The spring-clutches c, governed bymeans of thc'hand-lcvor D, connecting-mdf, lever k, and the counterinclined planes m, all arranged und operating substantially 'inthe manner and'for tho purposes set forth.
